Parameter Sensitivity of a Non-Linear, Process-Based Soil Erosion Model
Process-based, parameter distributed models have become widely accepted tools to predict the impacts of land use changes. Unfortunately these computer models are becoming more complex...
Estimating Watershed Runoff fro Lightning Data?A Case History
A major problem in the application of hydrologic models to ungaged watersheds is the lack of necessary rainfall data. In most cases watersheds gaged for streamflow have no or only one...
Spatial and Temporal Precipitation Characteristics in Southwest Idaho
The USDA-ARS, Northwest Watershed Research Center operates a precipitation gage network on the Reynolds Creek Experimental Watershed in southwest Idaho. Analysis of the 30-yr (1962-1991)...
Characterization of Thunderstorm Rainfall for Hydrologic Modeling
Rainfall and runoff records for 30 events from a 630-hectare subwatershed on the USDA-ARS Walnut Gulch Experimental Watershed in southeastern Arizona were used to estimate the desirable...
Analysis of Spatial and Temporal Precipitation Data Over a Densely Gaged Experimental Watershed
Historical precipitation data from the densely gaged Walnut Gulch Experimental Watershed in southeastern Arizona are used to quantify watershed-scale properties of precipitation. Daily,...
Watershed Simulation for Characterizing Droughts Under the Influence of Climate Change
The paper describes a model for simulating soil moisture deficit on a daily basis using historical rainfall and climatic data for the analysis of droughts. Distributed parameter hydrologic...
Comparison of Nested Models' Local-Scale Precipitation from a Three-Year Base Run and a Corresponding Doubled CO2 Run
Comparisons were made of nested model simulated precipitation from a 3-yr base run and the corresponding doubled-CO2 run for the Gunnison watershed...
Application of Distributed Parameter Watershed Model for Determining the Effects of Climate Change on Water Resources
Projected scenarios of climate change are likely to have significant effects on hydrology and water resources in the semi-arid western United States. The paper describes the application...
Nested Modeling of Watershed Precipitation
The U. S. Bureau of Reclamation's GCCRP (Global Climate Change Research Program) is concerned with the possible impacts of global change upon precipitation, environmental variables and...
Comparing Bowen Ratio-Energy Balance Systems for Measuring ET
Two Bowen ratio-energy balance (BREB) systems for measuring evapotranspiration (ET) under wet and dry conditions were compared. The study sites were an irrigated grass sod near Kimberly,...
Effect of Choptank Watershed Drainage Project on Stream Temperatures
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A conducted a stream study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of channel construction...
Watershed Erosion
Scientific agricultural planning requires knowledge of the relations between soil and water that cause soil loss, and of the procedure to reduce such losses on cropland. This paper presents...
Sediment Yields from a Watershed in Taiwan
Characteristics of suspended sediment load were investigated for Shih-Men Reservoir watershed in Taiwan. Results of the investigation showed that annual suspended sediment load was correlated...
Development of the Lake Okeechobee Watershed Phosphorus Transport Model
The Lake Okeechobee watershed phosphorus model was developed to route flows and phosphorus loadings associated with point and nonpoint sources through a watershed transport system, and...
Sediment Deposition in Jennings Randolph Reservoir, Maryland and West Virginia
The watershed of the Jennings Randolph Reservoir covers 263 square miles of mountainous terrain in western Maryland and West Virginia. Sedimentation studies performed prior to impoundment...
Sediment and Water Quality Control Devices in Small Watersheds
The physical behavior and health of an alluvial stream depends on the extent of man's interferences in its tributary areas. In its natural setting a stream provides three main functions...
GIS and SWMM Applications in Developing the Lake Houston Watershed Management Program
The City of Houston has undertaken the task of developing a Watershed Management Program for the 2,828 square mile lake Houston Watershed in an effort to prevent future degradation of...

Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...
Hydrological Aspects of Droughts
Two hydrologic aspects of droughts are investigated in this study as a part of the work conducted for the task committee on water management during droughts. In the first part a monthly...
